Few children make it through their first years without minor problems. Crying, problems with feeding, rashes, and an occasional fever are common. These problems become health concerns only when they are extreme—for example, when children cry too much, when they are not growing well, or when they have high fevers that do not go away. Most childhood problems are not severe. Very rarely, families face the tragedy of sudden infant death syndrome (SIDS).
